Abstract The environmental stability of 2D MXene flakes must be systematically studied before their further application. Herein, the colloidal dispersibility and photochemical delaminated Ti 3 C 2 T x modified with hydrazine (HMH) KOH water as control (HMH‐Ti , KOH‐Ti H O‐Ti respectively) are experimentally theoretically studied. Modification greatly increases flakes. Their critical coagulation concentrations 28.7, 106, 49.1 m NaCl, Hamaker constants 23.7 × 10 −21 19.1 37.7 J, respectively;...

<title>Abstract</title> Polymer dielectrics with enhanced thermal stability and electrical insulation are urgently needed for capacitive energy storage applications in electric power systems. There is a persistent challenge to break the contradictory correlation between high heat resistance low conduction existing polymers.

For the first time, we experimentally demonstrate a 400-Gb/s [4×100-Gb/s wavelength-division multiplexing (WDM)] pulse-amplitude-modulation-4 (PAM-4) transmission based on free space optics (FSO) utilizing polarization modulation (PolM) and direct detection (DD) scheme. Each WDM channel comprises modulator, polarizing beam splitter (PBS), two photodetectors (PDs). Four wavelengths each carrying 100-Gb/s PAM-4 signal (aggregate 400 Gb/s) are transmitted over space. At receiver side, PBS...
Constructing effective heterojunctions between semiconductors and appropriate cocatalysts exposing highly active crystal facets have been considered an approach to obtain efficient photocatalysts.

We first analyze the nonlinearities in analog radio-over-fiber (A-RoF)-based mobile fronthaul systems with a multi-user uplink load. The inter-band cross modulations (XMs) present common fiber channel cause severe inter-user interference. Then, we propose novel complex-valued multi-level artificial neural network nonlinear equalizer (ANN-NLE) for single-carrier frequency division multiple access signal transmissions. interference can be mitigated by employing ANN-NLE. Finally, design an...
